If you love DIY and celebrate Halloween, then you are in luck: you already have the pretext to venture into a new project maker for keep learning or showing off your advances with Arduino and Raspberry Pi.

Below you will find a careful selection to leave your own and strangers with your mouth open with these projects for which you need these versatile, compact and moderately affordable devices, some sensors and above all, time and imagination. Celebrate your Halloween maker in style!

Note: We have compiled some of the most interesting relatively affordable projects, with access to tutorials to carry them out and a suggestion of the main elements you will need, prioritizing in the purchase that they arrive in time for Halloween, although they are indicative lists.

The surprise guest

InvitedInvited

This project is not particularly difficult (although you will have to solder) and it is very well documented step by step with videos, as you will see later. It is also open to the imagination, since you can either opt for different masks, which may well be the classic horror masks or throw at something more current, such as one from ‘The Squid Game’, for example that of the terrifying girl from Luz Green, Red Light (22.99 euros). The idea is to place it in plain sight and make it sound and its eyes light up.

What do you need

Note: if you have more projects in mind, it pays to buy a pack of various colors (7.99 euros)

Preparing a potion in the cauldron

This is an ideal project for beginners, but not without its originality thanks to the ring of light. In addition, you can add complexity and spectacularity to the project by adding a smoke machine or gurgling sound if you wish. Of course, it is essential that you look for a great old casserole to achieve a more realistic effect.

All you’ll need to make something similar is a Raspberry Pi, a PIR sensor, a Bluetooth speaker, and a relay powering a light bulb.

What do you need

  • A Raspberry Pi with Wi-Fi (69 euros)
  • Sensor PIR (9,35 euros)
  • A relay module (10.99 euros) to power any light bulb
  • A Bluetooth speaker
